GEOLOGY

Detailed explanation-1: -Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice. Sediment can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by organic activity (e.g. as sea shells) or by evaporation.

Detailed explanation-2: -LIthification of sediment into sedimentary rocks takes place after the sediment has been deposited and buried. The processes by which the sediment becomes lithified into a hard sedimentary rock is called diagenesis and includes all physical, chemical and biological processes that act on the sediment.

Detailed explanation-3: -8 Sediments can be carried from one place to another. The movement of sediments by wind, water, ice, or gravity is called erosion. Sediments are dropped in a new location. The process of dropping sediments in a new location is called deposition.

Detailed explanation-4: -cementation, in geology, hardening and welding of clastic sediments (those formed from preexisting rock fragments) by the precipitation of mineral matter in the pore spaces. It is the last stage in the formation of a sedimentary rock.
